Features of the dose Badge Noise Dosimeters
| |
- No wires or controls on the badge to catch or knock
- Simultaneous, dual channel measurements:
- Channel 1, programmable exchange rate, time weighting,
criterion time and level
- Example: OSHA Q=5dB: Lavg, Dose %, TWA and Peak
- Channel 2
- Q=3dB (ISO): Leq, Dose %, Lep,d and Peak
- "A" frequency weighting with "C" weighting
for Peak
- Very rugged cast alloy case
- Powered by an internal rechargeable battery
- dose Badge and Reader communicate using an infra-red link
- Supplied with software to download measurements to a Windows
PC
- User programmable to either Q=3 (ISO) or Q=5 (OSHA)
- Time
History gives graph of noise levels
- Measures down to 70 dB(A)
- True Peak reading with Peak Time
History
- 115 dB(A) sound level exceeded flag
- Extra user-programmable settings for MSHA, AICHE and ACGIH
